Shaping sometimes fails. An oft-cited example is an attempt by Marian and Keller Breland (students of B.F. Skinner) to shape a pig and a raccoon to deposit a coin in a piggy bank, using food as the reinforcer. Instead of learning to deposit the coin, the pig began to root it into the ground, and the raccoon "washed" and rubbed the coins together.
ABA is an applied science devoted to developing procedures which will produce observable changes in behavior. [3] [9] It is to be distinguished from the experimental analysis of behavior, which focuses on basic experimental research, [10] but it uses principles developed by such research, in particular operant conditioning and classical conditioning.
The experimental analysis of behavior is a science that studies the behavior of individuals across a variety of species. A key early scientist was B. F. Skinner who discovered operant behavior, reinforcers, secondary reinforcers, contingencies of reinforcement, stimulus control, shaping, intermittent schedules, discrimination, and generalization.
For example, a child whose depressive behavior functions for negative reinforcement by stopping fighting between parents could develop a lifelong pattern of depressive behavior in the case of conflicts. Two paths that are particularly important are (1) lack or loss of reinforcement because of missing necessary skills at a developmental cusp ...
The professional practice of behavior analysis is a domain of behavior analysis, the others being radical behaviorism, experimental analysis of behavior and applied behavior analysis. [1] The practice of behavior analysis is the delivery of interventions to consumers that are guided by the principles of radical behaviorism and the research of ...
Applied behavior analysis is the discipline initiated by B. F. Skinner that applies the principles of conditioning to the modification of socially significant human behavior. It uses the basic concepts of conditioning theory, including conditioned stimulus (S C ), discriminative stimulus (S d ), response (R), and reinforcing stimulus (S rein or ...
For example, a circle swept along a straight axis would define a cylinder (see Figure). A rectangle swept along a straight axis would define a "brick" (see Figure). Four dimensions with contrastive values (i.e., mutually exclusive values) define the current set of geons (see Figure): Shape of cross section: round vs. straight.
As one moves around the circle, each octant reflects a progressive blend of the two axial dimensions. There exist a variety of psychological tests designed to measure these eight interpersonal circumplex octants. For example, the Interpersonal Adjective Scales (IAS; Wiggins, 1995) is a measure of interpersonal traits associated with each octant ...
